To all whom t concern:

it known that li, HERMAN d. Scmmrz,

a citizen of the United States, residing in the city of Chicago, county of Cook, and t State of Illinois, have invented certain new and useful Im rovements in Sheeting Machines, of which the following is a specification.

This invention relates to improvements'in i0 a sheeting machine and refers more particu larly to a machine for automatically cutting paper lsuch as wall aper, into` predetermined len hs to con crm with the design thereon. la Amon the objects of the invention are to provi e a machine in which a roll of a deslgned printed paper is fed therethrough and cut by a Severin means into predetermined lengths ixed y regulating elements operated from a central position to sever the sheet so that the severed len hs conform with the separate desi s printed on the sheet; to provide a machine whereb the rate oi feed of the aper may be spee ed or retarded at the will of the 'operator and a' secondary compensator operable to retard or advance the sheet to compensate for local irregularitiesin the desi w. Y

`Figs l and 2 are sieelevational views taken from opposite sides of the machine. Fig. 3 is an enlarged elevational'view oi the feeding mechanism. Fig. t is an enlarged view of the intermediate or central portion of the machine. Fig. 5 is a similar view of the delivery end ofthe machine. p

Fi 12 and 13ers detailed views showper mec 1 t s eet to the stack which de vers the seve than circular ves mounted on a lin printing wall paper samples, in ordr to show the complete effect of the side w and the border combination, rolls of wall paper are printed with the two designs printed on a single roll in a successive pattern so that when the roll is cut and mounted in asam le book form, the buyer can the eiiect o? the border and side wall pattern on a single sheet.

lt has been found on cutting these il into separate sheets that the length of'the design will vary due either to irre ularities in printing or to the character oft e paper stock, and from other causes.

rlhe ksheeting machine hereinafter explained, is constructed for the purpose oi cutting these sheets Ato conform? with the de'- sign on the paper roll, the-entire operation being regu ated by a single operator.

Briefly, the machine consists in a mechaf nisin for feeding the paper from a roll over a series of idler rolls and through a cutting mechanism. rlihe paper prior to being cut, ispassed over a vertical comnsating device which ma be raised lowered to` elongate or re uce the vertical loop in the v aper so that thels eed of the aper may e retarded or acce erated slight y to cause the cutting mechanism to conform with the design on the sheet.

Subsequent to its being severed the sheets are passed between tages to a gri ping mechansm by means of w ichf it is a vanced and From the straight ed the ypaper advances 'over the. idler rolls the latter rolls are ositioned slitters 9 t cli t the outside eges of the gm o a narrow strip of unprinte stock -or vage.

As explained the compensating mechanism is for the pur ose of retarding or advancingthe sheet 1n case of local irregularities in the design while the speed regulator is -more commonly used where the severing mechanism ycontinuously cuts ahead or back of the desired position. In case of the cutter failing to sever the sheet at the exact positionvbetween the designs the operator turns the hand wheel 74 either one way or .the other according to whether hev wishes to retard or advance the sheet. This hand wheel is connected through a rod 75 to a worm 76 meshing with the worm gear 77. Also mounted upon the shaft 78 to which the worm gear is fixed, are sprocket wheels 79 which drive similar sprockets 80 by means nof the chains 81. To each chain are attached vertically slideable bearings 82 which are slideably mounted upon the vertical rods 83. rlhe bearings 82 carry a transverse shaft on which the roll 19 is mounted. When the hand Wheel is turned in one direction the roll is raised on the vertically slideable shaft 83 so that the loop in the paper is made larger thus retarding slightly the travel of the pa er as the stock is taken up in the loop. Then the hand wheel '74 is rotated in the o posite direction, the

vertically slideable rol 19 is lowered and the paper loop decreased in height thus permitting the stock to advance faster, and as explained Ithe lower friction rolls 22 in Fig. 4 traveling at a somewhat faster rate of speed than the papertake up, the looseness produced by the lowering of the roll 19 by the compensating mechanism. 'Under normal conditions, the rate of speed of the roll 22 has only the eect of keeping the sheet taut and feeding uniformly to the cutting mechanism.

The sheet from the compensating loop passes' through the friction rolls, thence through the cutter` and is delivered to the conveyor tapes. These' upper and lower conveyor tapes are driven through the train of gears meshing with the large gear 8d mounted on the shaft 25 with the cutter as shown -in Fig. d. y

At the end of the conveyor tapes the severed sheets are gripped at their forward edge by the gripper mechanism mounted upon the chain 33 shown in Figs12 and 13. Contacting stops 32 are mounted on the shafts 33 fixed to the traveling chains above the surface of the sheet and tumblers 32b are pivoted at 32 onlugs likewise attached to the chains. a

As the chains running over the sprocket wheels 85 advance the tumbler mechanisms to a position shown in Fig. 12,. the machine drive is so timed that the severed sheet will be in aposition on the tapes as shown in the same gure, ready'to be'v engaged by the gripper mechanism.' The tumbler mechanism as it advances, has its lower depending leg 32d contacted by a pin 86 on thel arm 87. This rotates the tumbler about the pivot shaft 32c invertingl the position of the -tumbler and causing the enlarged head of the .tumbler to rotate about the .pivot 32 as an axis and grip the edge of' the paper sheet between the head of the gripper and the contacting sto 32a as shown in dotted lines in Fig. 12. n this position the sheet it withdrawn from the tapes and carried to a position over the paper stack or p-ile of severed sheets 34, at which ltime the second leg 32e which is set at an angle of approximately I50" with the leg 32d is contacted by pins 88 on the arms 89 rotating the tumblers to their former position out of contact with the stop32n as shown in dotted lines in Fig. 13. The gripper mechanisms then rotate with the c ains back to a position to grip the next oncoming sheet while the sheet falls upon the stack. The gripper mechanism is'driven by a drive chain 33a from the sprocket 25n mounted upon the shaft 25 to which the cutting mechanism is fixed as shown in 'Figs land 7. f Thus the entire machine operates in timed relation. The tumbler mechanisms are fixed to the chains 'by the pivot rods 32c and 32f.

lthrough the connecting rod 45 and arm 46 gives the side guides between vwhich the severed sheets are piled, an oscillating movement functioning to stack the sheets evenly, the pile thus having straight vertical edges and making it easier to-handle the sheets and aiding in the subsequent binding operation. rlhe details of the jogger mechanism are shown more'l clearly in 'Fig'. 11, the oscillating arm t6 `giving the shaft. 96 a like movement whic is transmitted to similar shafts 97 through the mitre gears 98. Depending arms 99 fixed to .the shafts contact ugs 100 mounted -upon the movable members-101. These movable members are fastened by spring 102 to the fixed brackets 103, thus as the guides 95 are attached to the movable members 101 when the latter are moved by the contacting of the lugs by the depending arms. the guide plates 95 will be given an oscillating movement similar to t of the depending elements 99 Ell@ due to the elideehle motion gdven muvo chie memher lOl hy the depending and spri 102. llt vvill he noted in h".
